Central areolar choroidal dystrophy

Overview

Central areolar choroidal dystrophy is a rare eye condition where the cells in the center part of the retina start to die. This can lead to a gradual loss of central vision, making it hard to see things clearly straight ahead. It is an inherited condition, meaning it can be passed down from parents to their children.

People with central areolar choroidal dystrophy may experience symptoms like blurriness or distortion in their central vision, as well as difficulty seeing fine details. The condition usually starts in adulthood and progresses slowly over time. While there is currently no cure for central areolar choroidal dystrophy, regular eye exams and monitoring can help manage the symptoms and preserve as much vision as possible.

How common is Central areolar choroidal dystrophy

Central areolar choroidal dystrophy is a rare eye condition that affects a small number of people. It is not something that many people have. It can be passed down from parents to their children, but not everyone who has a family member with this condition will develop it themselves. The chances of someone having central areolar choroidal dystrophy are low compared to other more common eye diseases.

This condition mainly affects the central vision and can cause blurry or distorted vision in the center of the eye. It can make it hard for people to see things clearly, especially when looking straight ahead. While central areolar choroidal dystrophy is not common, it is important for those who are diagnosed with this condition to work closely with their eye care provider to monitor and manage the disease to help preserve their vision.

Causes of Central areolar choroidal dystrophy

Central areolar choroidal dystrophy is when cells in the central part of the retina slowly die off. This can happen because of changes in certain genes that are responsible for keeping the retina healthy. Even though it can run in families, scientists are still trying to understand exactly how these gene changes lead to the condition. Other factors like age and environmental influences may also play a role in causing central areolar choroidal dystrophy.

Who is affected by it

Central areolar choroidal dystrophy is a condition that affects the eyes. It usually appears in adulthood and can cause problems with vision. It affects both men and women equally, and there is a genetic component to the condition. People who have a family history of central areolar choroidal dystrophy are more likely to develop it themselves. It is a rare condition, but it can have a significant impact on a person's quality of life if it affects their central vision. Treatment options are limited, and the progression of the disease can vary from person to person.

Types of Central areolar choroidal dystrophy

Central areolar choroidal dystrophy is usually divided into two types: Type 1 and Type 2. Type 1 is when there is a mutation in the gene known as PRPH2, which is important for the retina to function properly. This type typically causes central vision loss and difficulty seeing fine details. Type 2 is associated with a mutation in the gene CNGB3, which affects the functioning of the cones in the retina. This type often leads to color vision deficiencies and trouble seeing in low light conditions.

Both types of central areolar choroidal dystrophy are inherited in an autosomal dominant manner, meaning that a person only needs to inherit one copy of the mutated gene from either parent to develop the condition. Symptoms usually start in early to mid-adulthood and gradually worsen over time. While there is currently no cure for central areolar choroidal dystrophy, there are ways to manage the symptoms and slow down the progression of the disease. Regular eye exams and genetic testing can help diagnose the condition early and guide treatment options.

Diagnostic of Central areolar choroidal dystrophy

Central areolar choroidal dystrophy is typically diagnosed through a comprehensive eye examination. During this exam, an eye care professional will look for specific signs of the disease, such as the presence of drusen or pigment changes in the macula. Additionally, imaging tests such as optical coherence tomography (OCT) and fundus autofluorescence (FAF) may be used to further evaluate the retina and choroid.

Genetic testing may also be recommended for individuals with a family history of central areolar choroidal dystrophy, as certain gene mutations have been linked to the condition. In some cases, a visual field test may be performed to assess any potential loss of peripheral vision. Overall, a combination of clinical evaluation, imaging studies, and genetic testing may be used to accurately diagnose central areolar choroidal dystrophy.

Treatment of Central areolar choroidal dystrophy

Central areolar choroidal dystrophy is typically managed through regular monitoring of vision and eye health by an eye care specialist.
